Can I just hook up a c02 setup to my solenoid? What goes into a c02 setup???

I keep having a boost issue with a car and need to try to figure it all out...

 

Yes. All you need co2 bottle,regulator, and push lock fittings/hoses.

 

Its really not necessary for what you're doing. Manifold pressure works fine. Its all about having the right base spring pressure.

 

Or the right amount of backpressure.

 

can you please explain when would it be necessary using c02 boost controller?

 

In my opinion


Pros:

• Consistency of of applied pressure on top of the Wastegate diaphram
• Ability to run a very light wastegate spring and have the ability for high psi. "Wide Range of pressure"
• To answer your question BIG Boost.. if needed, and if you have a turbo to even support it.

Cons:

• Possibility of tearing Wastegate Diaphrams," yes it can happen"
• Leaks
• Refilling bottle
• Forgetting to turn on the bottle before a run
• Forgetting to turn off the bottle with a leak in the line

More of a hassle in my opinion, with a properly sized wastegate spring etc. You can run lots of boost, more than 98% of us will ever really need.

 

What kind of boost range are we talking about here?

 

5-50+

 

What size spring did you use to run? You were also divided ? This partciular car is running 1-60mm

 

!!!!!Some one is doing the home work early !!!!!

 

One of the cars I tune has a 8 psi spring and we've held 55PSI on it with no CO2.. Your just over complicating your setup..

 

with large turbos on small engine's (4 cyl) backpressure usually is not an issue and you can run with manifold pressure alone. On some large v8 engines backpressure is alot greater and most guys need to use C02 in order to get big boost... Although realistically they should just upgrade their turbos instead.

 

If your in a situation where your backpressure is high enough to blow your gates open you probably shouldn't be trying to add more boost. .

 

this is way over your head mr. fake 9.1 @ 165mph go blow another motor will ya!

 

Either way this car will not climb past 34-35 psi on the track we can get it to hit 45psi on the dyno with out any problems but once at the track she wont go past 34-35psi.

We have an 11psi spring in the wastegate

60mm tial wg

the manifold is divided with only one 60mm gate

Hondata S300 with mac valve

air to water IC 1,000 hp core

The source for the wastegate is coming from the compressor cover

I have tried to remap the duty cycle settings @ the track from my datalogs

What I have not done is added the diode to the mac valve which I am going to do tomorrow. I am also looking into getting a new mac valve and a bigger base pressure spring.

The car is running a BW S372r with 1.25ar turbine.

 

Thats not cool dude, Hope you don't Jinx yourself.

 

So whats the duty of the solenoid at 35 psi ?

 

Tsk tsk tsk tsk lol

 

try pulling your wastgate source from the manifold. You probably are making MORE boost pre intercooler then you are at the manifold so your gates are opening early. Try pulling it from the manifold and see if it helps.. It not then you have another issue somewhere, either backpressure a boost leak.

 

forgot I read this couple months ago and completely forgot...

I've been doing this homework for a month now, just trying to perfect the system. but i think s300 have its own limits when it comes to c02 or boost controller it self...
In MY opinion.
but hey what do i know im still new to the scene lol.

 

Wow this is all you have to add to the thread? Told you it was over your head.

 

I've noticed with C02 it holds the set boost more consistant and also makes the set boost faster. Without it I noticed boost creep up slower and drop off a little at a time

 

I've always heard you can only run 3 times what the wastegate spring is, so if you have an 11 psi spring, it should max out in the 30s but I could be wrong, if u need some springs I have some extra ones u can have

 

Ive run 8x spring with a 4 port solenoid.
